Duke Energy Carolinas, LLC Smart Grid Project
In addition to a $200 million grant for smart-grid improvements in Ohio and Indiana, Duke Energy Carolinas LLC, located in Charlotte, North Carolina, will receive $4 million for smaller smart-grid projects in North and South Carolina. The U.S. Department of Energy selected Duke Energy as one of 100 companies nationwide to receive federal funding as part of the American Recovery and Reinvestment Act of 2009.
Duke Energy’s (Duke) Phasor Measurement Unit (PMU) Deployment in the Carolinas with Communication System Modernization project upgrades the existing serial-based communications infrastructure across the Carolinas. This project includes the installation of PMUs and phasor data concentrators. An update to the existing energy management systems will be performed, along with visualization software to provide enhanced situational awareness for grid operators. Fifty-one substations across the Carolinas, at the 230 KV and 500 KV levels, are targeted to have the communications upgrade and approximately two PMUs planned per substation. PMUs provide high-resolution monitoring that improves grid operators’ ability to visualize and manage the transmission system, improving reliability and grid operations.<ref?Project Information Page</ref>
